Tiv tauj tswj thiab tiv thaiv tus kheej
Engineering tswj: kaw kev ua haujlwm thiab tso tawm hauv zos.Muab kev nyab xeeb da dej thiab cov cuab yeej ntxuav qhov muag.Kev tiv thaiv kab mob ua pa: thaum koj tuaj yeem raug cov plua plav, koj yuav tsum hnav lub npog qhov ncauj qhov ncauj qhov ntswg.Thaum muaj xwm txheej ceev lossis khiav tawm, nws raug nquahu kom hnav lub tshuab ua pa.Kev tiv thaiv qhov muag: hnav tsom iav kev nyab xeeb tshuaj.
Kev tiv thaiv lub cev: hnav khaub ncaws tiv thaiv kab mob.
Kev tiv thaiv tes: hnav hnab looj tes roj hmab.

Cov ntaub ntawv khaws cia thiab kev thauj mus los
Kev ceev faj khaws cia: khaws cia hauv qhov chaw txias thiab cua txias.Khaws kom deb ntawm qhov hluav taws kub thiab qhov chaw kub.Ntim thiab sealing.Nws yuav tsum tau muab cais tawm ntawm cov kua qaub thiab cov tshuaj uas siv tau thiab yuav tsum tsis txhob sib xyaw.Qhov chaw cia khoom yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog kom muaj cov xau.

Kev ntim khoom

Ntim txoj kev: Fiberboard chim, plywood chim thiab cardboard chim sab nraum lub hnab yas los yog ob-txheej kraft ntawv hnab;Lub thoob yas sab nraum lub hnab yas (khoom);Lub thoob yas (kua dej);Ob txheej ntawm lub hnab yas los yog ib txheej ntawm cov hnab yas, hnab yas woven thiab hnab latex ntaub;Cov hnab yas sib txuas sab nraum lub hnab yas (polypropylene peb hauv ib lub hnab, polyethylene peb hauv ib lub hnab, polypropylene ob hauv ib lub hnab thiab polyethylene ob hauv ib lub hnab);Tej rooj plaub ntoo sab nraum threaded iav fwj, hlau capped iav fwj, yas hwj los yog hlau chim (cov kaus poom);Lub raj mis iav, lub raj mis yas los yog tinned nyias steel phaj chim (tau) nrog lub qhov ncauj qhov ncauj yog npog nrog hauv qab phaj lattice lub thawv, fiberboard lub thawv los yog lub thawv plywood.
Kev ceev faj txog kev thauj mus los: Thaum lub sij hawm kev thauj mus los ntawm kev tsheb ciav hlau, cov khoom txaus ntshai yuav tsum tau sib sau ua ke nruj raws li cov khoom txaus ntshai sib dhos hauv cov kev cai thauj khoom txaus ntshai ntawm Ministry of Railways.Ua ntej kev thauj mus los, xyuas seb lub ntim ntim puas tiav thiab kaw.Thaum lub sij hawm kev thauj mus los, xyuas kom meej tias lub thawv tsis xau, tawg, poob lossis puas.Nws yog nruj me ntsis txwv tsis pub sib xyaw nrog acids, oxidants, zaub mov thiab khoom noj khoom haus additives.Cov tsheb thauj mus los yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm txheej ceev thaum thauj mus los.Thaum lub sij hawm thauj mus los, nws yuav tsum tau tiv thaiv los ntawm tshav ntuj, los nag thiab kub.
